7 Application filed. September This invention relates tohcuspidors and more particularly toa sanitary cover or rote'ctor for the mouth thereof. H

' The object of the invention is to provide a" cover whichmay be readily applied tothe funnel-shaped V which not only forms a sanitary protector therefor but also presents an adhesive surface which willtrapflies alighting thereon and thus preventthe spread of disease.

"Another object of the invention 1s to so construct the cover that' the 'blank from which itisimade may be firmly but release ably "held in engagement with the funnelshaped mouth of the cuspidor.

' A further ob ect of the invention isto coat the upper surface ofthe blank that the marginal portions thereof willbe prevented from sticking to an adjacent blank when severalof said blank svare nested for storage orshipme'nt' while at the same t me permitting the blanks to be, readily detached for use when desired.

This invention is illustrated in the accompanying drawing, wherein V Figure 1 is a view showing a cuspidor of a conventional construction partially in side elevation and partially in section with the improved cover applied thereto;

2 is a top plan view of the blank from which the cover is formed, and

1 each other.

Fig. 3 is a fragmentary sectional view taken on the line 33 of F ig. 2.

. The cuspidor to which the cover shown applied is of conventional construction and includes a bowl 1 having the usual funnel-shaped mouth 2. When a cuspidor of this type is in use, to accumulate upon the upper inclined surfaceof the funnel-shaped mouth instead of flowing into the bowl andwhen flies alight thereon they often carry germs and spread disease. This is one of the causes for the spread of tuberculosis and other similar diseases, and it is to prevent this spreading of disease germs by flies that the improved cover has been devised. v

The cover is preferably formed from a i paper blank shaped as shown in Fig. 2 but any other suitable flexible material may be employed capable of having its end portions readily moved into overlapping relation to The blank is segmental in shape and constitutes the major portion of a circle but the entire blank is not intended to be used whenforming the cover. Referring mouth of a cuspidor' and,

to Figs. 2 and 3,' itwill be seen that the marginal portion 3. of the blank has been offset from the body portion 4 by a line of depressions 5 which are pushed through from the upper face of the blankJ ,The, blank is scored injthi's manner in preference to a series ofslits'or other perforations'as it is desired to preventthe coating-of the. blank which will be hereinafter referred to from [leaking-through whenjafnumbe'r of blanks are stacked one upon another. ,The marginal portion 3 between the scored line 5 and periphery of the-blank is coated with rosin 1 so that when the blank is placed-Fin face to face contact with another blank the marginal portions will" not stick together and,therefore,- the blanks may be readily separated by first separating the marginal portions and pullingthem apart.

The portion; of the upper facewhich is ens.

closed by the scored linei coated with a sticky substance of a water-proof nature'a-nd serves toensnare flies which light upon it. Since it is water-proof any spittle deposited upon the cover will readily flow downwardly and pass into the bowl of the cuspidor'.

.Theformula preferably employed in com- I pounding the 'sticky substance consists of forty parts of rosin'dissolved in sixty parts.

of boilingcotton seed oil or. one pound of rosin dissolved in five pounds of hot twentyeight degree mineral oil; and four ounces of castor oil.v ;If desired a poison may be added so thatthe flies will be more quickly killed and their death insured if in any way they should succeed in escaping after alightingupon the sticky substance. It is further desired to prevent the sticky sub stance from penetrating the paper from which the blank is formed and causing it to be sticky on both sides and, therefore, the paper from which the blanks are stamped will be oil-proof. by impregnating the paper in a rubber solution, such as one ounce of washed dried Para rubber com pletely dissolved in one gallon of benzine to which is added one ounce of'carbon bi-,

sulphide mixed with sulphur chloride in the ratio of16.:1.' The cuspidor cover is primarily intended to prevent the spread of tuberculosis and, therefore, before thegpaper is coated with the sticky substance the wellknown tuberculosis symbol may be printed upon its upper face or a suitable legend, such as shown in; Figs. 1 and 2, inscribed thereon to call attention tothe fact that va person a should be careful to spit into the cuspidor.

When the cover is in use, the marginal edge portion 3 is separated from the main body of the blank by tearing along the scored line 5 and the end portions of the blank moved into overlapping relation toeach otherrto form a cover of an inverted frustro-conical shape. 'lVhen so cover will rest in flat contact upon the upper face of the funnel mouth 2 of the cuspidor, as shown in Fig. 1. In orderto retain the cover in place upon the mouthpiece, there has been provided tongues 6 which are anchored to the under face of the cover and, extend radially thereof with their free end portions extended beyond the inner periphery of the cover and adapted to be bent I into. engagement with the inner faceofthe cuspidor bowl. hen so positioned, the tongues serve to: very effectively hold the cover in place but permit of it being readily removed when it is desired to cleanthe cuspidor' and replace the cover withanew one. Before the cover is in use, the tongues may extend radially from the inner periphery of the blank or may be folded back uponthemselves beneath the body portion of the blank, as indicated by dotted lines in Fig. 2. These tongues may be formed of any material desired but it is preferred to em-,

ploy a strip 7 of thin sheet metal which may be easily bent and enclose the sheet metal shaped, the 7 tirely about said strip in spaced relation to the marginal edges thereof and defining a border adapted to be torn from the body of'the strip along the line of depressions, a'coating of sticky substance upon the upper face of saidbody within the confines. ofthe said line of depressions, a rosinous coating upon the upper face of said border, the

ends, of said body being overlapped after said border has been removed and secured by the sticky coating to form a concaveconvexed cover adapted to. fit snugly in a flared mouth piece of a cuspidor,an d fasteners carried by said body and projecting from the same and adapted to bebent into engagement with a portion of the cuspidor to retain the cover inplace.

In testimony whereof I aflixmy signature.
